TNS Media Intelligence/Campaign Media Analysis Group, CNN's consultant on political television advertising, has estimated that the cost to try to influence the 2008 election could exceed $3 billion. This is nearly twice as much than what was spent in 2004 when political and issue-advocacy television advertising rang in at $1.7 billion. In 2006, $2.3 billion was spent on political and issue-advocacy TV commercials.
